Thank you Yes it is that TTL changes in-flight. But my packets are captured on a specific link, there are only 2 or 3 kinds of packets. The way to distinguish them is only the TTL value. So here if IP.ttl doesnot work, how to instruct wireshark to handoff the 3 different kinds of packets to my 3 different dissectors? Thanks

The TTL value changes in-flight, so it cannot be meaningfully used to distinguish what protocol is being carried in an IP packet.In my specific situation, ip.ttl is my only way to distinguish my packets.What is your specific situation? What is it you're trying to do? ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
